Abstract
An image reading device is activated by the light interference of a light path. The image reading device comprises at least an image sensing element, a picture and an image changing mechanism such as a picture conveying module, picture rotating module, a hole or a soft button with a picture in the inner side. The user may use a finger or other objects to interfere with the image generated in the image sensing element. By detecting the changes of the image, a predetermined activation process of the image reading device is therefore started.
